Test video of the causes of water hammer occurrence.
Test video of the causes of water hammer occurrence.
We hypothesized that the cause of water hammer is related to flow rate and measured the internal pressure in the pipe at different flow rates. Additionally, water hammer can be recreated by gradually lowering the voltage when the pump stops.
basic information
Conditions Pump 50DWV5.75B Check valve is DYCV2 + shut-off valve is VP600D Piping height is 6.2m, water flow rates of 100L/m, 150L/m, 200L/m, 250L/m, and 270L/m will be tested in 5 stages.

Applications/Examples of results
In some cases, it is possible to reduce the output from 0.75 kW to 0.4 kW, which has energy-saving effects.
